Kubernetes: Storage Consistency and Kubelet Edge Fixes
API server storage work led the day with fixes for cache versus etcd error handling and delete preconditions, while kubelet addressed image garbage collection, pod readiness, and environment file bugs. Scheduler benchmarking and a webhook security limit round out the activity.

Good morning, it's Monday, October 5th, 2026, and this is your Kubernetes briefing.
The through-line today is correctness under failure and restarts, with parallel pushes to make API server storage behavior consistent and to stop kubelet edge cases from looping.
First, storage. PR 142591 surfaced mismatches in error handling between the watch cache and direct etcd storage, including get requests with bad resource versions and not-found handling. Related cleanup in PR 142633 moves watch cache reads to go only through snapshots, while PR 142671 preserves the resource version…
Second, kubelet and node lifecycle. PR 142669 fixes age-based image garbage collection deleting freshly pulled images when a pod never starts a container, which had caused a pull-delete cycle every few minutes. PR 142668 ensures pods are marked not ready when the controller restarts and finds its node already…
Finally, scheduler preparation and hardening. A new performance benchmark in PR 142679 establishes a baseline for workload-aware preemption on a near five-thousand node cluster. On security, PR 142674 caps webhook authorization responses at ten megabytes to prevent memory exhaustion. For API hygiene, PR…
